Solution:

Difference between C3 and C4 plants
About eighty-five % of total plant life species are C3, and the most effective 15% are C4 vegetation.
C3 plants are photosynthetic flora, while C4 are tropical plants.
C3 vegetation is said as cool-season flora even as C4 plant life is said as warm-season flora.
C3 plant life has a high rate of photorespiration, whereas C4 has a low rate of photorespiration.
C3 plants cannot lessen photorespiration, however, C4 plant life can lessen it too.
C3 carries out photosynthesis most effective while stomata are open, however, C4 can perform photosynthesis even if stomata are closed.
C3 plants need 12 NADPH and 18 ATP for glucose synthesis while C4 flora wants 12 NADPH and 30 ATP. This means C4 plants require 12 additional ATP as compared to C3 plants.
